I consider time evolution of observables after a sudden change of the magnetic field in the transverse field Ising chain. I present analytic results for the relaxation of order parameter correlation functions. These are interesting as the order parameter is nonlocal with respect to the elementary excitations. I discuss the interpretation of these results in terms of a generalized Gibbs ensemble.
